IMPROVED SKATE.

Specification forming part of Letters Patent No. 49,741, dated September 5, 1865.

To all whom it may concern:

Be it known that I, DAVID J. FARMER, of Newark, in the count-y of4 Essex and State of New Jersey, have invented a new and useful Improvement in Skates; and I do hereby declare that tho following is a full, clear, and ex! act description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanyingdrawings, forming part of this specitication, in which- Figure 1 represents a sectional side eleva tion of this invention. Fig.2 is a plan or top view of the same, the toe-plate having' been removed to expose the working parts. Fig. 3 is an inverted plan ot' the toe-plate.

Similar letters of reference indicate like parts.

This invention relates particularly toa new andimproved method ot attaching the skate to a boot or shoe; and it consists in the use of a stationary disk forming the guide for two or more radially-sliding hooks, the inner ends or shanks ot' which catchiu a scroll rising from or sunk in the surface of a revolving plate, two such scrolls. and hook-carrying disks being employed, one under the heel and one under the toes; or, if desired, only one such disk may be used under the heel, the toe part being secured by any other suitable means in such a manner that when the f'ootof the skater has been adjustedthe heel on the heeleplate and the toes on the toe-plate-the skate is readily fastened by simply turning the scrolls in the proper direction, whereby the hooks are made to catch simultaneously from different sides over the edge ot' the heel and ofthe sole, and by turning the scroll in the opposite direction the hooks are simultaneously withdrawn and the skate is unt'astened.

ln order to prevent the scrolls turning back spontaneously they may be provided with ratchet-teeth which engage with a spring-pawl attached to the stationary heel or toe plate, and which have to be raised when the skate is to be unfastened.

A represents the runner of my skate, which is made in the ordinary or any suitable manner. From this runner rise two studs, tt ct', one to support the heel-plate B and the other to support the toe-plate U. Said studs are round, and form the bearings for plates D D',

which are provided with a long hub, Z) b', and to which a rotary motion can be imparted by inserting` a suitable pin or rod into holes c in the hub, or by anyother suitable means. The upper surfaces ot' the plates D D' are provided with scrolls d, which are either sunk in, as shown in the d rawings,or which may be raised, and the form of which is shown particularly in Fig. 2. Said scrolls act upon the shanks ot' hook-catches c c', which slide in and out in radiating grooves fin the under surfaces of the plates D D', as shown particularly in Fig. 3. Two or more such grooves may be iliade in each of the plates to receive a corresponding number ot' hook catches. The points of the hook-catches are sharp, so that the same readily bite into the leather ofthe sole or heel, and said catches arc so placed that their points are at equal distances from the center of the scroll. By turning the scrolls in one direction the hook-catches move. in toward the center, and by turning them in the opposite direction they move out from the center.

The plates B C are rnily secured to the upper ends of the studs a a' by screws or any other suitable means, and ifdesired, one or both ot' them may he furnished with springcatches g, which engage with ratchet-teeth cut in the Aedges of the revolving plates D D', so that the scrolls are. prevented from receding spontaneously. In fastening the skate the hook- -catches e e' catch simultaneously over the edges of the sole and over those ofthe heel, and the spring-catch holds the scroll in position.

Then it is desired to unf'asteu the skate the springcatch has to be raised before the scrollv can be turned back.

l claim as new and desire to secure by Letters Patentl. The use of a scroll, D or D', in combination with radially-sliding hooks fitted into the heel-plate or toe-plate ot' a skate, or in both, substantially as and for the purpose described.

2. The application of a spring-catch, g, 1n combination with the heel-plate or toe-plate, or with both, and with the revolving scrollplates D D', substantially as and for the purpose set forth.

DAVID J. FARMER.
